Re: what's gaussian and single-pole exponential decay pulse
Hi Valiant,
An exponential decay pulse:
0 for t<0
k*exp(-t/tau) for t>=0
is the impulse response of a single pole low-pass filter.
If you apply an impulse to a cascade of many identical low-pass stages (it doesn’t matter their shape, it’s enough they are identical), the result is asymptotically a gaussian pulse:
